[Libdlo] module loads and unloads

[Alan Bell]

OK, the kernel module is in the right place and gets loaded, the xorg 
module is in /usr/lib/xorg/modules/drivers/displaylink_drv.so and gets 
loaded, but then it unloads again

(II) UnloadModule: "displaylink"
(II) Unloading /usr/lib/xorg/modules/drivers//displaylink_drv.so
(II) UnloadModule: "fbdevhw"
(II) Unloading /usr/lib/xorg/modules/linux//libfbdevhw.so

here is my /var/log/Xorg.0.log

I suspect the issue is to do with the error on line 138
(EE) open /dev/fb0: No such file or directory

but I am not sure what to do about it. Any clues?

Alan.
